2. If the head of your bed points north it will be a boy and if it points south it will be a girl (or vice versa…can’t remember). Jason: Again, this is not based in medical fact. In any event, who is to say what position the couple in question were facing during the baby making?? This along with all the other theories on determining a baby’s sex (the ring test, fast heartbeat = girl, etc) are all nonsense. BUT If someone can tell me how having a penis will change the way a baby lies in the uterus or a vagina can make a heartbeat change its rhythm, well then I’d be onto something!
